Rocket Sled Test of NASA’s Ultra-Precise Moon Landing Technology

January 28, 2020

it’s pretty exciting because the
administration is currently pursuing a path that is employing both robotic
exploration of the moon and planning to put humans back on the moon in 2024 this
kind of technology that’s behind me is exactly the kind of thing that we need
to be able to do this autonomously in DL navigation Doppler lidar is a sensor
that provides the very cause velocity and position as is making its descent
maneuver it it replaces the radar sensors that been
used in the past the NDL being a laser as opposed to a radar has three to four
orders of magnitude higher frequency that means more precise measurements
more this is a very unique technology and it’s nice to be able to see in the
field that it’s working to its potential measuring speed accurately had a long
range it’s something that we’ve never tested before so it’s very exciting to
be part of that and and see for the first time that we see that range and
velocity being measured we are doing this work under this blights project it
splices integrating a bunch of technologies together and one of the
pieces of that of it is this NDL sensor and it has three laser beams that are
sent down to the surface and then a reflection is received back and on each
beam we can tell exactly how far the surface is away and how fast we’re
moving along the surface and towards the surface in the L now is on the verge of
developing a spaceflight version to go on a couple of unmanned vehicles to the
moon hopefully we’ll be doing that in the next two years in DL provides
technology to allow to enable precise safe landings on the moon you
